  • 3D-MID - Prodution Steps

Characterisation of 3D-MID for Space applications

Customer: European Space Agency (ESA)

3D-MID Technology (using injection moulded thermoplastics) enables the integration of mechanical, electronic, optical and thermal functions into three-dimensional designs via selective metallisation, offering a high geometric design freedom and supports the miniaturisation of electronic devices. Applications such as position sensors, actuators, switches, and antennas can benefit from the manufacture of complex structures and shapes offering potentially significant savings in space, mass and weight, that cannot be realised with conventional electronic manufacturing methods.

The term MID can also include mechatronic integrated devices taking into account the fact that the three-dimensional carriers do not necessarily have to be injection moulded thermoplastics. Other materials, such as ceramics and thermosets can also be used, allowing the integration of sensors in complex structures or the integration of shielding, cooling and housing for optimal miniaturisation and weight saving. Even thermal functions such as heat dissipation and cooling can be realised using thermal conductive substrate materials and fully metallised surfaces.

Main Benefits of 3D-MID Technology

Optimal space utilisation via high functional integration density of mechanical & electronic functions on one component

MID enabled designs allow more efficient Assembly, Integration & Test (AIT)

  • miniaturisation with significant weight savings
  • high level of precision in the ultra-fine conductor range
  • 3D layout permits defined angles between components, stacking and precision placement of components
  • reduction of assemblies through reduction of conventional interconnect devices (e.g. strip conductors directly in the enclosure)
  • rationalisation and overall system simplification via reduction of process steps, number of parts and mounting time
  • increase in manufacturing reliability due to fewer mechanical parts and processes
  • full three-dimensionality with through plating allows complex three-dimensional interconnect devices
  • production with high variance and short changeover times. Layout change of the conductor network needs no tools, just a change of the CAD layout data

«POLAR»
(in Space)

Gamma Ray Burst Polarimeter «POLAR»

Customer: European Space Agency (ESA)

Despite being discovered in 1960 (Vela satellites) Gamma Ray Bursts (GRBs) are still full of mystery and the production mechanism of these very intense explosions in the universe is still unknown. To validate – or exclude – existing models about their creation, a precise measurement of the polarisation of the GRB is essential.

«POLAR» is a highly sensitive detector using the Compton Scattering Effect to measure the polarisation of incoming photons. With its large Field of View and a detection energy up to 500 keV «POLAR» will measure the polarisation of GRB emissions using low Z material Plastic Scintillators, multimode Photomultipliers and multi-channel ASIC Front-end Electronics. «POLAR» is scheduled for two to three years operation in space during which a large number of GRBs are expected to be measured.

Seismometer Electronics

Customer: Contraves Space AG

The NETLANDER mission planned to send a network of four identical landers to the surface of Mars to perform simultaneous measurements in order to study the internal structure of Mars, its sub-surface and its atmosphere. To fulfil the mission objectives with respect to the interior, subsurface, atmosphere and ionosphere investigation of MARS, each the 4 landers was to carry a payload composed of nine instruments. The Seismometer Electronics «SEIS-EL» control the legs of the measurement sphere, the internal seismic instruments and a variety of sensors.

Our Contribution

With a mass of the surface modules limited to 22kg, of which only 5.2kg was allowed for scientific instruments, the ultimate goal was to estimate possible mass / volume reductions (and cost) and to provide a recommendation for the most suitable approach and technology. Art of Technology conducted a System Analysis, Feasibility Study and Technology Evaluation of the main and auxiliary controllers and motor drive electronics, including:

  • SEIS Main Controller Electronics (SEIS-MC)
  • SEIS Acquisition Controller (SEIS-AC)
  • critical properties review
  • evaluation of High Desity Packaging technologies
  • identifying IC (ASIC) technology for implementing (digital) circuits
  • review miniarturisation potential and component availability
  • identify achievable mass volume and power for FM circuits
  • analysis of development and qualification costs for FM models
  • STIX - Solar Orbiter Experiments

The Solar Orbiter payload accommodates a set of in-situ and remote-sensing instruments, with a total payload mass of 180 kg.

STIX – Detector Electronics Module «STIX-DEM»

Customer: European Space Agency (ESA)

Art of Technology (together with prime contractor Almatech Sarl) was awarded a contract by the European Space Agency (ESA) for the design, development, production and supply of the Detector Electronics Module (DEM) to be used in the «STIX» instrument… a Swiss experiment on board Solar Orbiter, scheduled for launch in 2019.

Mission Objectives

Solar Orbiter will travel to within 45 million km of the Sun (¼ of the distance between the Earth and the Sun, closer than any other spacecraft to date allowing a portion of the surface to be observed for longer periods of time without interruption. The Solar Orbiter mission will address the central question of helio-physics, i.e. how does the Sun create and control the heliosphere?

The «STIX» instrument

Developed and built under the direction of the University of Applied Sciences Northwestern Switzerland, the «STIX» instrument will provide observations of the sun with unprecedented sharpness and direct measurements of solar winds and charged particles close to their point of origin. This new orbit will allow us to study the Earth side facing away from the sun and for the first time, the polar regions.

«STIX» will contribute to understanding the mechanisms behind the acceleration of electrons at the Sun and their transport into the interplanetary space. «STIX» will also play a key role in linking remote-sensing and in-situ observations on Solar Orbiter with imaging spectroscopy of solar thermal and non-thermal X-ray emissions providing quantitative information on the timing, location, intensity and spectra of accelerated electrons as well as of high temperature thermal plasmas, which are mostly associated with flares or micro-flares in the solar corona and chromosphere.
